When attempting to rescue a person who is drowning, one must approach the situation carefully. The reason being the rescuer is in danger of being pulled under by the one needing salvation. That is also true spiritually and Jude gives us the warning.
Jude 22-23
And on some have compassion, making a distinction; but others save with fear, pulling them out of the fire, hating even the garment defiled by the flesh.
Many are perishing, but be careful out there in your rescue attempts. Give it some thought.
